Collmenter (10-8) has given up only four earned runs while delivering five straight quality starts, and he gave up his first home run in that stretch in the fourth inning Tuesday. After his offense got the run back in the sixth, Collmenter fell behind again on a sacrifice fly in the seventh. He owns a 3.60 ERA, 1.17 WHIP and 107:38 K:BB ratio in 165 innings. Collmenter is scheduled to face the Twins Monday in what should be his last start of the season.
Peavy (7-13) continued his run of excellence Tuesday, with the only damage coming on an RBI single in the sixth inning. He's allowed a total of three earned runs in his last five outings, and he hasn't given up more than two earned runs in any of his last seven starts. Peavy owns a 3.82 ERA and 151:59 K:BB ratio in 190 2/3 innings, but he's posted a 2.29 ERA since coming to San Francisco. He's scheduled to face the Dodgers Monday.
Siegrist (1-4) has now surrendered at least one earned run in six of his last nine outings, with Tuesday's blemish coming on an RBI single in the 12th. His ERA has jumped from 3.86 to 6.30 since the end of July, and the reliever owns a 37:12 K:BB ratio in 30 innings.
Rosenthal walked the first batter of the ninth inning before surrendering a double to put two runners in scoring position with no out. After a groundout couldn't advance the runners, the closer intentionally walked the next batter to load the bases with one out but blew the save on a sacrifice fly. He owns a 3.31 ERA and 85:41 K:BB ratio in 68 innings.
Lynn watched the offense score two runs in the bottom of the first inning and was able to maintain the lead throughout the game despite serving up a solo home run in the fourth inning, but the bullpen blew his lead in the ninth inning to deny him a win. He's now allowed exactly one earned run in three straight starts. Lynn owns a 2.68 ERA and 167:69 K:BB ratio in 191 2/3 innings. He's scheduled to face the Cubs Monday.
Peralta gave up a pair of runs in the first inning, one on a bases-loaded walk and another on a double play, and though he settled down from that point on, the offense was unable to pick him up until the ninth inning. He owns a 3.70 ERA and 137:57 K:BB ratio in 184 2/3 innings. Peralta is scheduled to face the Pirates Sunday.
While the opposing starter allowed five runs on only four hits, Matzek (6-10) was able to scatter 11 hits while only allowing a two-run double in the sixth inning while already up 5-0. He's held the opposition to two earned runs or less in five straight starts and now owns a 4.19 ERA and 83:41 K:BB ratio in 111 2/3 innings. Matzek is scheduled to face the Diamondbacks Sunday.
Haren (13-11) watched a run come home on a groundout and another on a wild pitch in the first inning. He then gave up another run on a groundout in the second inning before serving up a two-run home run in the fourth. It was the first time in five starts Haren surrendered more than one earned run. He owns a 4.14 ERA and 134:36 K:BB ratio in 174 innings heading into Sunday's scheduled matchup with the Cubs.
Elias gave up two earned runs on five hits and one walk in three-plus innings and struck out one before having to come out of the game. He's scheduled to pitch again Sunday against the Astros, but his availability is obviously tied to the status of his elbow.
Altuve tied Craig Biggio's franchise record of 210 hits with a double in the fifth inning Tuesday, and No. 211 came on a seventh-inning single. The major-league leader in batting average, Altuve has hit .343/.379/.456 with seven home runs, 54 RBI and 52 stolen bases in 616 at-bats. He has 11 more games to add to his new record.
